Servicers

(5th) Business Day of each month, using a text file format. The data
consist of dates, amounts and codes housed in the servicer’s default tracking
system.

Each data
element is assigned an Update Code. This code is filtered through a
codes table in CitiMortgage’s default system during file upload that directs the
data to the appropriate field on our system. Each data element per
loan in the servicer’s electronic file must have an update code assigned to it
in order to upload into our system correctly.

servicer’s data extract is a comma-delimited rich text file
(RTF). The file is set up in rows of one data element per
loan. Each row contains the following 4 data elements:

in a DD-MMM-YYYY format (2 numeric characters for the day of the month, 3 alpha
characters for the first 3 letters of the month, and 4 numeric characters for

021046955,496265,004,12DEC2003

021046955,496265,005,13

021046955,496265,007,01JAN2004

420221154,784456,022,27DEC2003

In this
example, the first 3 rows of data correspond to bankruptcy filing date,
bankruptcy chapter, and bankruptcy post petition due date for loan
021046955. The last row of data represents the foreclosure attorney
referral date for 420221154. Leave no spaces between commas in a row
and sort the extract by MSD loan number.
